JSPlayer

JSPlayer is a simple gadget designed for the desktop that you can use to view video files in a very small panel. It is ideal when you're trying to multitask when working on a project, for example.

In order to use this tool, you must have Windows Media Player installed on your computer. The frame is very small and can be moved to any position on the screen using the mouse cursor.

JSPlayer supports the same array of media formats as Windows Media Player, such as AVI, MP4, MPG, MP3, WAV and OGG. It integrates standard media controls which let you pause the stream, create a playlist, play the previous or next track, and adjust the volume level.

Unfortunately, you cannot increase the frame size or switch to full screen mode. Although you can modify the frame's opacity level, all thanks to the default options provided by the operating system (as well as make the window stay on top of everything else), it is not possible to adjust the opacity of the image (it slightly blends into JSPlayer's background, making it a bit difficult to follow a clip).

However, the gadget is very light on the system resources, using a minimal quantity of CPU and RAM. It has a good response time and works well, without causing Windows to hang, crash or pop up error dialogs. It can be used with ease by novices. Unfortunately, JSPlayer has not been updated for a long time.
